The real reason why the burp smells so badly is hydrogen sulfide (H2S). If you eat foods that have sulfur proteins in them then you may find yourself burping the H2S, which will smell like rotten eggs. The sulfur reducing microbes in the intestine digest the proteins and release the gas.
When you have sulfur burps your body is creating a gas from proteins that contain sulfur. It is known as hydrogen sulfide gas. There are microbes in your digestive system that break down the sulfur and release it. Most often, these microbes are part of the âgood bacteriaâ and nothing to worry about.
